At baseline, 120 older adults performed the TUG 3 times; once in the standard way, once with a manual dual-task (carrying a glass of water), and once with a cognitive dual-task (counting backward in threes from a number between 60 and 100). The tests were performed in random order after a practice run. After this, participants were prospectively followed for 1 year to record fall incidents.
No significant results were found for the regular TUG or the TUG with a manual dual-task. For the TUG with the cognitive dual-task, a significant result was found, from which an appropriate cut-off point could be determined to set sensitivity and specificity of this prognostic test.
